As do all major Nvidia partners
As you may know, Far Cry 2 is a The Way It's Meant To Be Played game. Nvidia likes this game very much and has high hopes for it, so all major Nvidia partners, including Zotac, are doing a Geforce GTX 200 series bundle that will include this game.
Zotac is just the latest one that has boarded the Far Cry 2 gravy train and it is going to bundle this Ubisoft's FPS with its GTX 280, GTX 280 AMP!, GTX 260 2 and GTX 260 AMP2! Edition cards. It all started with EVGA, XFX, BFG and Inno3D and now Zotac.
We agree that Far Cry 2 is a nice addition to the card, but we don't share Nvidia's enthusiasm about the game, as Fallout 3 and Crysis work better for us.
